The command to get a modem to answer is ATS0=2 (where 2 is the number of 
rings to wait before picking up.)

You should set your port speed to at least 38400 to use a 28.8kbs 
modem..edit the ttyd1 line in your /etc/ttys file to read :-
 
ttyd1   "/usr/libexec/getty std.38400"  vt100   on  secure
 
You get out of tip with ~.

If your modem still does not answer it is prolly becuase it is 
confilicting with your existing serial board - ensure it IS on com2, and 
that nothing else is. Also check that it has an IRQ all to its self. 
(usually IRQ3 for com2)

If you initilize the modem with AT&D0 instead of AT&D2 the modem should 
answer wheather there is a conflict or not - it will however not hang up by 
itself when the remote user closes the session at your end. (so this is 
best used for trouble shooting only).

If you want to do dial back - it is best to get a modem with the 
capability built in (much easier, and prolly more secure too !)
